Applieation filed Gctober '1, 1926, Serial No. maeea, and in Germany July 26, 1926.

The invention relates to a stapling device for setting staples or the like in thicknesses of paper or cloth by means of a punch adapted to be depressed manually against the action of a spring, which punch on each downward movement ejects one of the staples from a bar or from a row, and on its upward movement, the next staple under the action of a 'feedin device is fed into position for the following operation.

Such devices are known. The new characteristic of the present device resides in such an arrangement of its parts that, in spite of the small dimensions and neatness of the whole device-permitting its use even on an ordinar writing tableits parts are easily detacha le and adjustable so that it ma be operated by any person without specia instructions, can be filled with a new set of staples on the others being exhausted and can be ad'usted for varying distances of the staple or astener from the ed e of the sheets tobe united, while faulty stap ing is avoided.

The accompanyin drawing illustrates various embodiments o the new stapling device.

In the drawings, Figs. 1 to 3 are side elevation, end elevation and plan of one embodiment.

Fig. 4 is a view corresponding to Fig. 2 with the setting positions varied.

Fig. 5 is a side elevation of the device in a form suitable for inserting staples in the folds of double sheets.

Figs. 6 and 7 are longitudinal sections through the device in inoperative and in operative positions of the punch, respectively.

Fig. 8 shows the feed mechanism and its engagement with the staple carryinbar.

Figs. 9 and 10 show in side elevation, partly in longitudinal section and in plan the pivot of the upper part and the base. Figs. 11 and 12are corresponding views of a modification of this pivot.

" As shown, the device consists in known manner an upper part A forming the housing for the staples, with the punch and feeding device, and a lower part or base B, to which the upper part is secured by means of a pivotG permitting of its being tilted for the insertion of the papers or the like to be fastened together.

The upper part A consists of a housing 1 of iU-shaped section in the form of a horn having an inwardly curved solid back with a front plate 2 and open only at the rear and i at its lower side. In the lower portion of the housing 1 is fitted a bar 3 held at the de-' sired distance from the side walls by rivets 4, such bar 3 serving as a support for the staples 5 arranged in a row thereon. In an 80 opening 6 of the.head.1 of the housing is fitted a punch 7 fitted with a handle 8 which carries a flat die 9. The head 11 of a screw 10 securing the die 9 to the punch, bears against the closing plate 2 and forms a guide for the punch. The die is formed with a slot 12. Between cheeks 14 on the closing plate and in a slot 20 therein is mounted a triangular locking member, 15, 16, I7, pivoting about a pivot 18. The lower arm 16 of the locking member always bears against the foremost staple or against the forward end of the staple support 3, while the upper arm 15, with its lug, bears on the solid portion of the slide or die 9, Fig. 6.

Above the staple support 3 is a feeding device for the staples 5. Such device consists of a rod 19 formed with a flange 21 at one end of a bail portion 22 serving as a handle at the other end which terminates in a tail 23. The rod 19 supports by means of lugs 25 a U-shaped slide 24 which is guided on the back of the bar 3. The rod 19 is surrounded by a spring 26 and due to the tension of the spring engages by its tail 23 an inclined openmg 13 in the bar 3, Fig. 8. The slide 24 is under the pressure of the spring 26 and is located behind the staples 5, a portion of'the rod 19 extending through the lugs 25 (Figs. 6 and 7). Since'the casing 1 is closed, preventing ingress of dust and the like, and has an inwardly curved back, it is possible to form. a return spring for the punch 7 asa blade sprin 27, and to secure it to the back by means 0 a rivet 29. Its free bent'end 28 engages beneath the punch 7'. The staple support has at its end projecting beyond the casing 1in the embodiment shown in Figs. 1 to 5-a circular opening 30 which extends into a horizontal slot 31. Through this opening extends a flat pin 32 disposed at an inclination, which pin is fastened in a bearing 33 in the base B. The base B, consisting of a plate 34 with lateral semi-circular grooves 35, is fitted with a Z-shaped spring 36, which serves to hold the upper part A at a distance from its upper face, and from the anvil 37 In the grooves 35 engage the horizontal arms of a wire bail-shaped member 39, formed with a central band 38. The distance apart of the arms 39 is so selected that they must be spread somewhat to allow the arms 40 to be inserted in the grooves 35, so that the bail is clamped to the base. The otherwise usual guide slot, in the base, for limiting the extent to which the papers or the like can be inserted is thus dispensed with. The bail serves as a limit of the extent to which'the papers to be fastened together can be inserted, and its distance from the front edge of the housin determines the distance of the fastening rom the edge of the sheets. Thus, if papers or the like are to be fastened in the fold of double sheets, as a result of which the sheets must be introduced very much below the upper part, there is used a very long base B, with a rod-like ex- I tension 41 secured to one end, which extension is forked at 33 at its opposite end. The arms of the fork carry the inclined flat pin32 I Fig. 5. The upper part A, which is adapted to pivot about the pin 32 with its circular opening 30 in the staple support 3, in order that it may be passed over the base B, is moved into the inclined position shown in Fig. 5, so that the slot 31 extends in the direction of the pin 32 and can be withdrawn therefrom. In the reverse manner it can be fitted over the pin 32 of ,the extension 41 of the base B.

Instead of forming the base of a solid plate it can be formed of a hollow pressed sheet metal strip B and the grooves 35" formed as lateral extensions, Fig. 4. As a result the device, the casing 1, 1 ofwhich preferably consists of light metal, will be lighter" in weight-a particular advantage of the present invention.

While in the embodiment shown in Figs. 1 to 5 of the drawin s the pin of the pivot G is rigidly mounte in bearings 33 on the base B, or in the fork-shaped arms 32 of the projecting rod 41, and the upper part A with I its opening 30 in the staple support can pivot about the pin 32 and because of the slot 31 can be withdrawn therefrom in a particular inclined position (see in particuular also Figs. 9 and 10), the pivot G may be mounted on the staple support. In these circumstances the flat in 32 is arranged horizontally and the bearings 33 on the base B are provided with a circular opening 30", and a slot 31 extending at an inclination thereto and of a width equal to the thickness of the pivot pin 32 (Figs. 6, 11 and 12).

To prevent faulty stapling the above-mentioned locking device consisting of a doublearmed lever 15, 16', is rovided. The arm 16, with the die in raise osition, bears against the foremost staple, w ile the other arm 15, with its lu bears against the solid part of the die. I the die is depressed then the projecting staple tilts the double-armed lever 15, 16, about its pivot, so that the arm 15 engages in the slot 12 in the die. In this position the double-armed lever 15, 16, holds the die until the staple, now in the delivery channel, is completely ejected. If the-punch be only partly depressed, then, since the arm 15 engages with its lug in the slot 12, the punch cannot return under the action of the spring 27. Onl when the foremost staple or fastener is e ected can the die carry the arm 15 with it and rotate it in such manner that the arm 16 again lies in front of the succeeding sta 1e.
